What is Black Teflon Tape?
Peflon Black Teflon Tape is a thin film made from chemically inert PTFE resin, formed into a pure PTFE sheet and coated with a pressure-sensitive silicone adhesive. It is widely used to seal threaded pipe joints, protect electrical insulation, and handle high-temperature or corrosive environments in industrial and mechanical settings. The base polymer, PTFE (CAS 9002-84-0), belongs to the fluoropolymer family commercialized by upstream producers such as Daikin.
Chemical Resistant
Stays strong against acids, oils, fuels and solvents.

FAQ of Black PTFE Tape
What is the main application for black PTFE thread seal tape?
Black PTFE thread seal tape is used to seal threaded pipe joints. The black color serves as a visual identifier, commonly specified for gas-line connections so installers and OEM assemblers can distinguish safety-critical joints at a glance.
Can black PTFE tape be specified for water lines as well as gas?
Yes. Although black is typically color-coded for gas service, the PTFE film seals water and other fluid threads just as effectively as white tape. Density and thickness can be matched to the media and pressure class of your application.
Does black PTFE tape differ from white tape in material?
No — the base material is the same high-quality virgin PTFE. The difference is the color coding used as a visual indicator for specific services such as gas lines. Standard, high-density and customized-density options are all available.
What density of black PTFE tape should we specify for high-pressure connections?
For high-pressure systems and larger-diameter threads we recommend our high-density black tape, which is thicker and provides superior sealing. Standard-density tape is sufficient for everyday plumbing, and where safety margins are critical we produce customized-density tape to your specification.
What is black PTFE coating, and how does it differ from tape?
Black PTFE coating is a finish applied to metal parts to create a low-friction, non-stick, corrosion-resistant surface. It is a different product format from thread seal tape, though it is made from the same PTFE base material.
